Quiet a racing mind. Sleep like you used to.
Biopeptide by Kincadence is a melatonin-free nightly capsule with 150 mg of α-casozepine, a clinically studied milk peptide that supports your brain’s own calming signal — for how you sleep, and how you handle everyday stress.
Meet Biopeptide
One capsule before bed. Calm, sleep and everyday stress support, without a nightly hormone.
Quiets a racing mind
Helps your brain’s GABA calming signal land harder, so switching off at night comes easier.
Eases everyday tension
Takes the edge off everyday worry and the clenched, on-edge feeling that follows you to bed.
Supports your stress response
Supports a healthy cortisol response, so the same pressures hit with less force.
Clear mornings
Non-hormonal and not a sedative. No melatonin, no morning grogginess.
It works with your calming signal, not around it
One capsule, 30 to 60 minutes before bed
A single vegetable capsule. No powders, no stacks, no timing puzzle.
α-casozepine supports GABA
GABA is the signal that tells your nervous system it is safe to stand down. Biopeptide works with it instead of adding a hormone or a sedative.
Calm rather than knocked out
The stress response settles so sleep can come on its own, and you wake without the fog.
What to Expect as Your Nervous System Winds Down
The Mental Chatter Quiets
As α-casozepine begins working with your GABA pathways, the constant mental noise starts to settle. Early changes are usually subtle.
Physical Tension Eases
Stress doesn’t only live in your head. As your system calms, the clenched-jaw, tight-shoulders, restless feeling starts to loosen.
Your Stress Response Steadies
With the calming pathway better supported, day-to-day stress stops hitting as hard. You react to the same pressures with more of an even keel.
Steady Days, Not Just Calmer Nights
As better sleep and a steadier stress response compound, the daytime payoff shows up: less of the drained, wired burnout.

What is Kincadence?
Kincadence is a US supplement brand from Longevity Hub LLC in Wilmington, Delaware. We build focused daily formulas around clinically studied, named ingredients at the doses used in the research, starting with Biopeptide, a melatonin-free capsule for sleep and everyday stress.
What is Biopeptide and how do I take it?
Biopeptide is a once-nightly vegetable capsule with 150 mg of α-casozepine, a bioactive peptide from milk protein. Each capsule also contains 300 mg of magnesium glycinate and 25 mg of apigenin. It is melatonin-free, non-hormonal and non-habit-forming. Take one capsule 30 to 60 minutes before bed, or two on harder nights.
What is α-casozepine?
α-casozepine is a peptide released from αs1-casein, a milk protein, by enzymatic hydrolysis. It has been studied in placebo-controlled human trials for everyday stress and sleep quality. It works with GABA, the brain's own calming signal, instead of adding a hormone or a sedative.
Why do I keep waking up at 3 AM?
A nervous system that stays switched on at night is one common reason people wake in the early hours and cannot drop back off. Biopeptide is built for that pattern: it supports your brain's calming signal so the stress response can settle, without sedating you.
How is Biopeptide different from melatonin?
Melatonin is a hormone that signals the time of day to your body clock. α-casozepine is not a hormone and does not act on your body clock; it works with your brain's own calming pathway. Biopeptide contains no melatonin, so there is no next-day fog.
How is it different from magnesium, ashwagandha or valerian?
Magnesium is a mineral your body uses for hundreds of processes, and ashwagandha and valerian are herbs with broad effects. α-casozepine is a single, specific milk peptide with its own human studies on stress and sleep, and it works with the GABA calming signal directly. Biopeptide is built around that peptide, with a modest 300 mg of magnesium glycinate (33 mg elemental magnesium) and 25 mg of apigenin, every dose on the label, so you know exactly what you are taking.
Will it make me groggy? Is it habit-forming?
No on both counts. α-casozepine is not a sedative and is non-habit-forming. The effect is calm rather than knocked out, and there is no morning grogginess.
How long until I notice a difference?
Calm support is often felt within the first week, while sleep quality tends to build over two to four weeks of nightly use. Individual experiences vary, so give it a full month for the best read. Every order is covered by a 90-day money-back guarantee.
Who is Biopeptide for?
Adults whose stress follows them to bed: the 3 AM waker, the tired-but-wired, people on shift or travel schedules, and anyone in midlife who wants to sleep and handle stress the way they used to. It is for men and women alike. It is not intended for children.
Does it contain dairy? Is it vegan or gluten-free?
Biopeptide contains milk. α-casozepine comes from milk protein, so it is not vegan and not suitable for anyone with a milk-protein allergy. It is gluten-free and contains no caffeine or melatonin.
Can I take it with medication, or while pregnant or nursing?
α-casozepine is a food-derived milk peptide that has been well tolerated in clinical studies. Even so, if you are pregnant, nursing or taking medication, ask your doctor before use.
Where is it made and how is it tested?
Biopeptide is made in a cGMP facility and third-party lab tested. Every ingredient and its dose is printed on the label. There are no proprietary blends.
Where do you ship, and what is the guarantee?
We ship to the United States, Canada and Australia with tracking. Standard shipping is free on orders over $60. Every order comes with a 90-day money-back guarantee: if you do not feel the difference, we refund you.
